A nickname favored by adolescent girls for Sephiroth, the main villain of Final Fantasy VII. Also used in a derogatory manner concerning Final Fantasy VII fanboys- see GameFAQs for additional information. I mean, Jesus, Sephiroth could not beat Megaman.
Sephiroth: "
Wah,
wah, I can't destroy the earth with a giant meteor! I want my mommy."
Megaman: "Hello, I have a
GUN FOR AN ARM and I DESTROY
CRAZY ROBOTS FOR A LIVING, then CONSUME THEIR BODIES to fuel my destructive ways."
